well i dont have hdmi input to my video card but hdmi-hdmi cable i have.
so if i will buy dvi-hdmi cable do you think it will help?
even then, i think its not the problem because it worked on the last X1950XTX and Windows 7 64-bit so i think its something with the driver.
it installed a generic display driver and i even tried to instale non-generic display driver and it has not helped...
well a 4890 and a x1950 are 2 different chips. honestly i cant say that's why my last resort was and hdmi cable.
oh before i forgot, did you properly uninstall your previous card's drivers? did you driverswept? (google driversweeper)
